I think if you made money or had your best ever day today, you should be worried about your long term trading future. Most expereinced traders on the desk today i know, did not do particularly well.
While at lunch I went bankrupt and was back to normal by the time I got back. Kind of glad I missed that. God I hope the jobs report is good tomorrow. I'm long and damn it sucks having a cash account waiting for it to settle.
i agree with the OP- yeah this graph looks terrible on a daily, weekly or even monthly basis- back it out a year-- can you say "profit taking at any cost"?
This wouldn't happen. The trade would have been tagged as clearly erroneous and broken. For high $ stocks, anything past 3% from the last verified price is broken. Given the obvious issues with a rule like this, in practice this rule is very much a guideline rather than a strict formula. Regardless, if you were filled anywhere below 234 or so in aapl, your trade got busted.
